Error: Start-stop (BlueGT 2017)

[Volkswagen]

Hi,

Two days ago I started my BlueGT 2017 (60300 km / 37500 mi) in the morning. I felt that the engine was not running well, causing "shaking" feeling in the cockpit. Soon after this the yellow engine light started blinking, and there was a text "Error: Start-stop".

A day before this incident, I drove about 70-80 km/h (43-50 mp/h) and I felt this "twiching" feeling when driving this constant speed. The feeling was like the car going "back and forth". I have DSG.

I called technician about this, and he said it might be the battery because I haven't replaced it since 2017.

I still wonder why there wasn't any battery sign light, just the start-stop if the problem is the old battery.

NOTE: The yellow engine light and the "Error: Start-stop" text are not constantly there, I started the engine again today and there were no signs of them.

Any other possible reasons for the yellow engine light and "Error: Start-stop" text?

Thanks in advance!

Did you ever sort this? I have had the same problem, but it won't be the battery as I only had this replaced 2 3/4 years ago.

Rear error codes to start with

The legendary "Rear Error Codes"... (damn stupidphone)

But jokes aside, while you are on your way to the back of the car, you might accidentally trip over the engine bay. If you happen to drop an OBD scanner there by mistake, keep an eye out for those fashionably late P030X codes.They usually appear when one of the cylinders decides to take an unscheduled coffee break instead of sparking joy.

It’s a classic symptom when certain coiled components up front start feeling a bit tired after a few years, making the whole car shake like an old washing machine on its spin cycle...

My issue turned out to be the coilpacks. I swapped my APR ones over (that had been fitted 2 1/2 or 3 1/2 years ago) with the original VW ones that had been running OK with before and I wasn't getting the warning symbols as often, but it still wasn't running fully right and the engine warning light came up twice for a short period. I ended buying some new Delphi coilpacks (as they were meant to be one of the best aftermarket ones) as genuine new VW ones were over twice the price and also some new NGK sparkplugs. I would not mind paying that if I know that that is what the issue was, but if it wasn't it's a lot to pay when you still haven't sorted the problem. Anyway, luckily since they were both fitted, it's been fine since

Well done! Both are high-quality brands.
Thanks for the report.
